<div class="block">Classes to perform curve fitting.

 Curve fitting is a special case of a least-squares problem
 where the parameters are the coefficients of a function \( f \)
 whose graph \( y = f(x) \) should pass through sample points, and
 were the objective function is the squared sum of the residuals
 \( f(x_i) - y_i \) for observed points \( (x_i, y_i) \).</div>
